SIEECIFICATION forming part of Letters Patent No. 674,532, dated May 21,1901.

Application filed August 18, 1900. Serial No. 27,315. tNo model.)

To all whomit may concern:

Be it known that I, CHAUNOEY H. BOOTON, aciuzen of the UnitedStates,residiugat Gallipolis, in the county of Gallia and State of Ohio,have invented a new and usefulAutomatic Register-Gage forPrintingPresses, of

which the following is a specification.

This invention relates to an automaticallyoperating register-gage forprinting-presses,

and contemplates the provision of simple and. effective means of thischaracter for causing an accurate registration of the sheet withoutrequiring precise manual adjustment thereof and permitting a press to berun at a materially greater rate of speed than heretofore with acorresponding increase in the output of work within a specified or giventime and a more satisfactory result vin the quality of the work andmarked economy in the use of '20 material, the gage being applicable toany form of platen-press and used only on one side of the tympan andoccupying no more space than the ordinary side pins now in use andserving to place the sheet in proper position irrespective of a regularor irregular feed of the same.

The invention consists in the construction,

combination, and general organization of the several parts of the gagein general and in 0 detail, which will be more fully hereinafter.

described and claimed, and subject to a wide range of modification,whichwill be indicated hereinafter by reference to the several variations,and also indicating that other changes in the form, size, proportions,and minor details may be resorted to without departing from theprinciple of the'invention.

In the drawings, Figure l is a perspective view of a portion of a press,showing the gage 40 forming the subject-matter of thisinvention appliedthereto in operative position. Fig.

2 is a detail perspective view of the gage.

Fig. 3 is a top plan view of the same Fig.

is a section on the line 5 5, Fig. 3. Fig. 6 is a section on the line 66, Fig. 3. Fig. 7 isa detail perspective view of parts of the device,

showing a modification in the construction.

Fig. 8 is a detail perspective view of a portion of the operating-arm,showing a further modification. Fig. 9 is aplan view of a p0rtion of theimproved device, showing aslight modification.

Similar numerals of reference are employed to indicate correspondingvparts in the several views.

The numeral 1 designates a supportingplate, preferably constructed ofthin metal of a non-corrosive nature and having adjacent one end, nearthe outer edge, a pair of fulcrum ears or lugs 2, having a longitudinaldirection relatively to the plate and spaced apart from each other asuitable distance for the pivotal reception of the rear bifurcatedterminal 3 of an operating-arm 4 and normally held outward or away fromthe plane of the plate 1 by a spring 5, engaging the pivot thereof andof such strength to always. cause the said arm to return to its outwardnor-] mal position when free to do so. This operat-. 7o 4 ing-arm can beconstructed in many-different designs and be supplied with variousattachments to render it more convenientin application to difierentstyles of printing-presses and more efficient in its operation. One ofthe most important of these attachments or convenient provisionsconsists in a sliding ex tension 6, having a rear terminal guide 7,movable on the said arm and both engaged by a looking or clamping slide8 for holding the parts against accidental movement after a desiredadjustment has been obtained. It will be observed that by the use ofthis attachment the arm may be operatively lengthened or shortened tocompensate for the proportions of various kinds of presses, and at itsinner end the said extension has an outward projection 9 at an anglethereto for contact with a gripper or other part of a press, which willcause the arm as an entirety to be 0 pressed close to the plate 1, andthus actuate change is indicated by Fig. 8 and consists in too mountingan antifrictional bearing-roller 10 in the inner or contacting terminalof the arm for use in connection with that class of presses that do notemploy grippers and to bear against the press-body or furniture adjacentthe tympan, and in this instance the said arm will be used without theextension, though there may be instances where this featureof the rollercould be effectively employed in connection with the said extension, andsuch use of the roller is contemplated.

At the inner end of the plate 1 transverse guides 11 are secured andhave their opposing edges inclined to form a dovetail seat for thefreely-movable reception of a slide 12, having opposite beveled sideedges and an inner angular head 13 at a right angle thereto andproviding What may be concretely termed a pusher or slidablesheet-placer. The slide 12 has an outwardly-projecting stud 14 toreceive the inner end of a retractile spring 15, attached at itsopposite end to a suitable projection 16 on the plate 1. This spring mayat times be dispensed with, as will be hereinafter set forth; but whenused it operates to return the pusher or placer to normal position, andthe automatic operation of the latter device to perform the function forwhich it is devised is caused by the operating-arm and intermediateconnections between the latter and said pusher or placer. The head ofthe pusher or placer is engaged by the outwardly-deflected innerterminal of a controllinglever 17, which is loosely disposed on andunattached to any part of the slide or head, the rear or oppositeterminal of the said lever being pivoted to or fulcrumed on the plate 1.The outer edge portion of the lever, adjacent the pivot or ful crumthereof, is provided with an open socket 18, as clearly shown by Figs. 2and 3, and loosely engaging therewith is a ball 19 on the inner end of aconnecting screw-shank 20, having a polygonal fixed collar 21 foradjusting the same relatively to asocket 22, carried by a ball 23 andmaintained in adjusted position by a jam-nut 24. The ball 23 looselyengages an open socket 25 on the inner edge of the arm 4, and thus adouble ball-andsocket connection is formed between the lever and arm,which has a normal upward inclination from the lever toward the arm andthe alternate depression of the arm, and the return of the same to itsnormal position in an automatic manner by the action of the spring 5will cause a differentiation in the distance between the contiguousedges of the lever and arm and alternately force the lever inward anddraw the said lever outward and correspondingly move the pusher orplacer inward and free the latter for outward normal position. When nospring is used for retracting the pusher or placer, the slide thereofwill be provided witha pin 26, as shown by Fig. 9, for engagement withthe free end of thelever to return the said pusher or placer to normalposition, and the sockets for the balls at the opposite ends. of theconnection in this instance will be closed, as

shown. Itwill also be understood that the forms of connections set forthwill prevent jarring or abrupt vibration of the lever, and the pusher orplacer will consequently always have a regular stroke, and this latterdesirable movement of the lever will also be due largely to theelongated construction of the arm, and therefore no matter howrapidlythe ment, and between these two sockets a stiff link 28 is interposedand formed with terminal balls 29, located in said sockets. From thisshowing it is to be understood that the adjustable feature of theball-and-socket connection is not essential to the practical operationof the gage, and when the last-described ball-and-socket connection isused the retractile spring for the pusher or placer can be dispensedwith and the pin 26 (shown by Fig. 3) substituted in lieu thereof andwhich is an obvious substitution.

In applying the improved device to the tympan, as shown, it is preferredthat the tympani-sheet he of a strong and durable nature to support thegage attachment without tearing. The under side of the plate 1 issupplied with a layer of glue or other adhesive material and placed onthe said tympansheet, and in theevent that the device is not evenly orregularly positioned the irregularity can be rectified by adj usting thescrewshank 2O relatively to the socket 22 to cause the pusher or placerto havea regular stroke. The operating-arm is regularly positionedrelatively to the gripper at one side or other part, and the sheet to beprinted is fed to the machine and rests against the usual pins or stopsextending outwardly beyond the ty mpan-sheet, and as the parts of thepress are moving the operating-arm is pressed toward the plate 1, andthereby actuates the pusher or placer to dispose the fed sheet in properregistering position in an easy yet quick manner without jar or jolt.The portion of the head ofthe placer or pusher that normally rests closeto or against the inner edge of the plate 1 projects slightly beyond theinner plane of said plate to compensate for the layer of glue or otheradhesive material and cause the innermost edge of said head to bearclosely against the tympan-shcet, and thereby always insure engagementof the head with the sheet edge and prevent the latter from workingunder the plate. The pressure on the operati ngarm will be exertedagainst the inner free end of the same in the direction of the outerside of the same and not against the endin a longitudinal direction, andconsequently the inner end of the plate will be forced firmly IIOagainst the tympan-sheet, and thereby also tend to hold the head of thepusher or placer in close operating relation to the tympansheet.

It will be observed that the gage has been devised and is equipped withmeans for overcoming the complex structure and unsatisfactory operationof previous devices of a similar character, and it will be particularlynoted that the organization of coacting members are compact and close inwithout material projection to avoid interference with the working partsof a press and that it occupies very little room. The use of only one ofthe devices is necessary, and the cost of manufacture and application isreduced to a minimum from a comparative standpoint. ln fact, the pressesare permitted to run at such a great-er degreeof speed with positiveresults and accurate work by the application of the gage embodying thefeatures of the invention that the operation of the press of whateverkind is materially reduced in cost, as the capacity of the same isincreased by the rapid feed permitted by the gage with accurate resultsand a better quality of work than has heretofore been attainable with aslower movement.

Many other advantages will appear to those using the improved device,and it will be appreciated that the'gage is not confined in itsapplication to any particular style or kind of press.
